Actually you will get some units of energy from splitting some quantity of water into hydrogen and oxygen, then LESS energy from converting it back to water. The Second Law of Thermodynamics demands and increase of entropy and therefore an increase in temperature > loss of energy to heat.

"Often" means, what? Compared to what? One of the anthrax vaccines seems to be associated (notice I didn't say "caused") with systemic lupus and other autoimmune illness. There are clearly more cases of SLE among young men in the military than there are cases of anthrax.
There were less than 10 cases a year of polio from the live vaccine yearly in the US before we switched back to inactivated vaccine, but there were even fewer cases of wild type polio.
Risk applies to populations, if I get Guillian-Barre syndrome from flu vaccine I don't get 10^-6 cases, I get it 100%. It's a lottery, you pays your money and you takes your chances.
Of course vaccines have advocates, they are big money like everything else in medicine in the US and elsewhere. Varicella (chicken pox) kills or cripples few people every year, but costs megabucks (or gigabucks, depending on who's numbers you read) in lost work with parents staying home with sick kids. Still, that might be the big vaccine manufacturers talking like Microsoft saying there are billions lost yearly to software piracy.
I will be willing to take an HIV or Hepatitis C vaccine should one become available since I'm exposed to body fluids in my work, just like I took the Hepatitis B vaccine. Is it worth the risk? I may be too old to die from hepatitis C if I contract it, it takes 20 to 30 years to kill you - unless you are the one in a few hundred it kills in a few years . . . (BTW, I'm not a porn star, in case you were wondering)
The phenomenon of "If every body is vaccinated the disease dies out" is herd immunity. That does not work against some viruses and bacteria that are in the world like Tetanus. Smallpox has been eradicated. In the USA there WAS more vaccine related polio than wild polio, so we've switched to the killed (Salk) vaccine over the live (Sabin) vaccine. Other parts of the world still use Sabin because it works better, and 5 cases a year are better than 50,000.
Maybe we are weakening our immune systems by not having diseases, or by being too clean - farm kids have fewer allergies and less asthma in the US.
Increases in life expectancy aren't because folks get to be lots older, it's mostly because fewer children die before they can get old.
Me, too. Seriously, there was an article in Scientific American and an interview by the author of this on "Science Friday" who predicted that should humans disappear, rats and cockroached would suffer - they are essentially commensals (or parasites?) of humans. With us gone they would suffer greatly reduced populations. There is an article in this month's Scientific American about how cockroaches can live for several weeks without heads, it has two photos of regular cockroaches on the age, I forced myself to read it. PTSD from the apartment I lived in in college.
